Subtract and check your answer by addition: T O 5 2 - 3 7 T O +

We need to subtract 37 from 52 and check the answer by addition. First, let us subtract the digits in ones place. As 2 < 7 , we borrow 10 from the tens place digit. Subtracting ones place after borrow: 12 - 7 = 5 Subtracting tens place after borrow: 4 - 3 = 1 4 12 5 2 - 3 7 1 5 Now, let us check the subtraction by addition. To check the answer using addition, we add two smaller numbers. If the sum is equal to the bigger number, the obtained answer is correct. Here, two smaller numbers are 37 and 15 . 1 3 7 + 1 5 5 2 Hence, the obtained sum is equal to the bigger number. Therefore, the given numbers are subtracted and checked using addition.

Subtract and check your answer by addition: T O 6 5 - 2 9 T O +

We need to subtract 29 from 65 and check the answer by addition. First, let us subtract the digits in ones place. As 5 < 9 , we borrow 10 from the tens place digit. Subtracting ones place after borrow: 15 - 9 = 6 Subtracting tens place after borrow: 5 - 2 = 3 5 15 6 5 - 2 9 3 6 Now, let us check the subtraction by addition. To check the answer using addition, we add two smaller numbers. If the sum is equal to the bigger number, the obtained answer is correct. Here, two smaller numbers are 36 and 29 . 1 3 6 + 2 9 6 5 Hence, the obtained sum is equal to the bigger number. Therefore, the given numbers are subtracted and checked using addition.

Subtract and check your answer by addition: T O 7 4 - 4 8 T O +

Given: To subtract 48 from 74 and check the answer by addition. First let us subtract ones 8 from 4 . So, we regroup 74 as follows. 74 = 7 tens + 4 ones. = 6 tens + 14 ones. Write 6 in tens column and 14 in ones column as shown below. 6 14 7 4 - 4 8 Now, subtract the ones. 14 ones - 8 ones = 6 ones. Thus, subtract the tens. 6 tens - 4 tens = 2 tens. Hence, 6 14 7 4 - 4 8 2 6 The answer is 26 . Now, let us check the subtraction by addition. To check the answer using addition, we add two smaller numbers. If the sum is equal to the bigger number, the obtained answer is correct. Here, two smaller numbers are 48 and 26 when we add. 48 + 26 , we get 1 4 8 + 2 6 7 4 Hence, the obtained sum is equal to the bigger number. Therefore, the given numbers are subtracted and checked using addition.

Subtract and check your answer by addition: T O 8 7 - 1 8 T O +

Given: To subtract 18 from 87 and check the answer by addition. First let us subtract ones 8 from 7 . So, we regroup 87 as follows. 87 = 8 tens + 7 ones. = 7 tens + 17 ones. Write 7 in tens column and 17 in ones column as shown below. T O Borrow : 7 17 8 7 - 1 8 Now, subtract the ones. 17 ones - 8 ones = 9 ones. Thus, subtract the tens. 7 tens - 1 tens = 6 tens. Hence, T O Borrow : 7 17 8 7 - 1 8 6 9 Now, let us check the subtraction by addition. To check the answer using addition, we add two smaller numbers. If the sum is equal to the bigger number, the obtained answer is correct. Here, two smaller numbers are 18 and 69 when we add. 18 + 69 , we get T O Carry : 1 1 8 + 6 9 8 7 Hence, the obtained sum is equal to the bigger number. Therefore, the given numbers are subtracted and checked using addition.

Subtract and check your answer by addition: T O 6 7 - 4 9 T O +

Given: To subtract 49 from 67 and check the answer by addition. First let us subtract ones 9 from 7 . So, we regroup 67 as follows. 67 = 6 tens + 7 ones. = 5 tens + 17 ones. Write 5 in tens column and 17 in ones column as shown below. T O Borrow : 5 17 6 7 - 4 9 Now, subtract the ones. 17 ones - 9 ones = 8 ones. Thus, subtract the tens. 5 tens - 4 tens = 1 tens. Hence, T O Borrow : 5 17 6 7 - 4 9 1 8 Now, let us check the subtraction by addition. To check the answer using addition, we add two smaller numbers. If the sum is equal to the bigger number, the obtained answer is correct. Here, two smaller numbers are 18 and 49 when we add. 18 + 49 , we get T O Carry : 1 1 8 + 4 9 6 7 Hence, the obtained sum is equal to the bigger number. Therefore, the given numbers are subtracted and checked using addition.

Subtract and check your answer by addition: T O 9 4 - 5 9 T O +

Given: To subtract 59 from 94 and check the answer by addition. First let us subtract ones 9 from 4 . So, we regroup 94 as follows. 94 = 9 tens + 4 ones. = 8 tens + 14 ones. Write 8 in tens column and 14 in ones column as shown below. T O Borrow : 8 14 9 4 - 5 9 Now, subtract the ones. 14 ones - 9 ones = 5 ones. Thus, subtract the tens. 8 tens - 5 tens = 3 tens. Hence, T O Borrow : 8 14 9 4 - 5 9 3 5 Now, let us check the subtraction by addition. To check the answer using addition, we add two smaller numbers. If the sum is equal to the bigger number, the obtained answer is correct. Here, two smaller numbers are 35 and 59 when we add. 35 + 59 , we get T O Carry : 1 3 5 + 5 9 9 4 Hence, the obtained sum is equal to the bigger number. Therefore, the given numbers are subtracted and checked using addition.
